Healthy Lemon Bars

Here they are…. healthy vegan lemon bars!

Healthy Vegan Lemon Bars

I said I was going to make healthy lemon bars this summer and I finally did it! Vegan and naturally sweet!

2 years ago I gave Ina Garten’s lemon bar recipe a natural makeover. I thought I had conquered the world of traditional desserts because they were a perfect replica. To be more specific, my husband couldn’t tell the difference and everyone I tested them on adored them. A real feat because her lemon bar recipe is the best, right?

Now a couple of years later, with a little more knowledge and experience, I wasn’t going to stop there. I was going to make lemon bars without a pound of butter, sugar or eggs! So without the traditional ingredients, these healthy lemon squares are better for you. They still have that famous shortbread base and thick lemon filling. And contain that divine sweet to tart ratio flavor that is found in Ina Garten’s recipe.

So how on earth did I make lemon bars without butter, sugar or eggs that still tasted delicious? There’s a secret ingredient! It’s brilliant!

It’s agar-agar!. Agar-agar (or sometimes just called agar) is made from seaweed and is often used as a gelatin substitute. (If you didn’t know, gelatin is made from boiled animal ligaments and sinews so that’s not vegan-friendly either.)  It can be a little expensive, but you never need much! For a 9″ by 13″ pan of these healthy lemon bars that are also super thick and filling – you’ll only need a tablespoon of agar! So your vegan investment will last a long time. That is, if you can resist making these lemon bars every other week!

Agar-agar is wonderful because when we add it to lemon juice and natural sugars, it will become deliciously thick and will take on the flavor of citrus. It holds a wonderful shape, so you get perfect lemon squares every time. The texture is a bit different from traditional bars, but they will feed any custardy craving! All this without refined sugar or unhealthy dairy products. Yep, the best of both worlds – these are a taste of vegan goodness to the max!

Print Recipe

2 1/3 cups White Spelt Flour or Organic White Flour
3/4 cup Xylitol or Powdered Honey or Maple Sugar (powdered honey is my fav for this part)
1/4 teaspoon Baking Powder
1/8 teaspoon Sea or Pink Salt
1 1/3 cups Earth Balance Butter
1/2 teaspoon Natural Butter Extract (optional)

2 cups Water
1 Tablespoon Agar-Agar Powder (not Agar-Agar Flakes)
1 1/4 cup Xylitol OR 3/4 cup Xylitol and 1/2 cup Powdered Honey
1 Tablespoon Liquid Stevia
1 teaspoon Pure Vanilla Extract
1 1/2 cups Fresh Lemon Juice
2 Tablespoons Cornstarch (decrease to 11/2 Tablespoons if using powdered honey)
2 Tablespoons Fresh Lemon Zest (about 6 Large Lemons)
2-3 drops Natural Yellow Food Coloring (optional, but recommended for a true yellow color)

Prepare the crust:
In a large bowl combine the flour, sweetener, baking powder and salt. Mix well to combine. Cut in the earth balance butter in to the mixture until it looks like almost like a moist pie dough. Scoop out the mixture and press into a slightly greased 9 by 13 or 11 by 7 pan for thicker bars (like pictured). Press gently around the edges to create a crust so the filling will hold well. Place in the freezer for about 5 minutes.

Preheat the oven to 350 degrees. Bake the crust for 20 minutes. Remove the pan from the oven and allow to cool. Next, start on your filling.

In a saucepan, soak the agar and water in a sauce pan for 2 minutes.

After the agar has mostly dissolved, turn on the heat to high and boil for about 2-3 minutes until the agar is completely dissolved. The mixture will boil and bubble up, so just lift the pan up from the heat if it rises too much. Mix in dry sweetener and stevia. Turn down the heat to medium and add the cornstarch, lemon juice and lemon zest.  Whisk constantly over a low simmer until the mixture thickens slightly and everything is dissolved, about 3-5 minutes. Turn off the heat and add the vanilla extract and the food coloring, if desired.

When everything has dissolved, pour over the crust. Don’t worry that the mixture isn’t very thick at this point, it will stiffen up in the fridge! Allow to refrigerate for about an hour, until the filling is slightly wiggly but firm and has set. Sprinkle or sift some powdered xylitol, regular xylitol granules or powdered honey over the tops. Slice into bars and devour! Store any leftovers in an airtight container in the fridge.


* For some reason, the dusted sweeteners on top of the lemon filling dissolved really quickly. You can try adding a bit of flour to your sweetener to help keep the sugars from dissolving, but texture of the lemon bars are just moist and very porous. Because of this, dust with sweeteners immediately before serving. They also don’t really need any added sweetener on top, so just omit entirely if you don’t care about the white dusted layer.

    If the boyfriend weren’t still sleeping, I’d be jumping up and down and shouting Eureka! These are incredible! I had never heard of agar agar, but this opens the door for all sorts of amazing bar treats! Good going, ladies, I’m going to go to the natural food store and go shopping for lemon bar ingredients!!

    I love lemon bars, but I cannot tolerate stevia (yea, I know its all natural and all – but it leaves me with a very bad taste). Would you substitute with more honey powder?

    • says

      Stevia is not equal to powdered honey, so it does become a little tricky. You could try subbing with 1 tablespoon of powdered honey and then decrease the cornstarch by another tablespoon.

      • says

        Also, I would like to add that the stevia adds extra sweetness to combat the tartness of the lemons. If you use more powdered honey as a substitute, I would decrease the lemon zest by 1/2 a teaspoon just so you don’t have an overly tart lemon flavor. Good luck with those changes!

    I’m really looking forward to trying these! I double checked to make sure but I’m not seeing cornstarch listed in the crust ingredients, but it looks like it’s supposed to be included. Is this wrong? If not, how much? Lemon bars have got to be one of the best foods on earth! YUM! Thanks in advance :)

    I’m curious about powdered honey, because I’ve never heard of it before.
    Is it actually dehydrated honey or is it a vegan honey-flavored product?

      • Rasha says

        It’s cool if you’re into powdered honey, but please don’t call these bars vegan if they contain animal products. I was so excited to see this recipe at first, until I realized I couldn’t eat it.

        • says

          Hi Rasha, We realize not all vegans eat honey, which is why xyltiol is offered as another option. If you don’t want to use the powdered honey, you can use the xylitol. Thanks!

  5. says

    I just had lemon bars the other day and they made me think of these! The ones I had were the ‘pound of butter’ type, but honestly, I couldn’t tell that much of a difference between those and these. Great pictures too!

    Holy moly, these are delicious!! Wow. The texture is different, but the flavor is spot on. I will have to fight myself not to eat the whole pan before the husband comes home.

  7. Linda O. says

    One other substitution question: I can’t have Xylitol as it gives me headaches. (have no idea why) Would I substitute all powdered honey for the Xylitol in the filling recipe?
    Appreciate your help.

    • says

      Hi Paige! Glad you like the recipe. We give the option for honey because we know vegans who truly avoid all animal products except for eating honey, so saying they are vegan is an easier description than saying “dairy-free, egg-free, gelatin-free, leather-free”, etc. Thanks for your comment! :)

      • Kristin says

        Agave nectar is a good and easy substitute for honey. There are also mock honey substitutes like bee-free honey, or there’s maple syrup, brown rice/malt syrup, coconut nectar, yakon syrup, even molasses. There is never any reason to eat honey.


  1. Hi, I was wondering if you’ve made this without agar agar, but just still use the dairy-free substitutes. I can have eggs, but can’t have dairy. Can this work with eggs?
